In most companies, millennials are already a significant percentage of the workforce, so it’s important for current leadership to understand common ground and areas of divergent thinking. In this executive summary, we give an overview of the differences among generational cohorts based on interviews, surveys, and focus groups in 14 organizations. Our research confirmed our hypothesis that differences are more likely attributable to life stage than inherent generational differences. We learned that, generally, millennial leaders aren’t that different from other generations and from CEOs, but there are important caveats. For example, millennial leaders may be fearless, or unafraid to speak up, but they’re also risk averse.
